I am needing to access the ABM API via C#. Searching has directed me to use BouncyCastle. I have downloaded the PEM file. However, using the following: using (var reader = File.OpenText(pemFilePath)) { var pemReader = new PemReader(reader); var keyObject = pemReader.ReadObject(); I get the error "problem creating EC private key: System.NullReferenceException: Object reference not set to an instance of an object."

We are expering frequent delays recently when associating a device serial with the adamid of an app in our business manager account. I get an event id back when calling the /associate api but when i check the status of that event id is can be sat in a pending state for sometimes several hours. Need to understand why and if its a configuration issue

Why don't obtain equipment list (https://mdmenrollment.apple.com/server/devices) interface returns "device_family" contour information. This interface only returns some fields, and many field values are not returned

In iOS 26.1 beta 4, under MDM restrictions that disable the camera via a configuration profile, the Camera and FaceTime apps are hidden as expected. However, other third-party apps can still access and use the camera function normally. This is unreasonable.

I'm writing to point out a potential structural error in an example of the DeclarativeManagement command. This could cause significant confusion for developers implementing the MDM protocol. The standard structure for a server-to-device MDM command requires CommandUUID and the Command dictionary to be siblings under the top-level dictionary. The CommandUUID serves as a top-level identifier for the entire command envelope. This is the correct, expected structure: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>Command</key> <dict> <key>Command</key> <dict> <key>RequestType</key> <string>DeclarativeManagement</string> </dict> </dict> <key>CommandUUID</key> <string>0001_DeclarativeManagement</string> </dict> </plist> This is an example of the incorrect structure I've seen: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>Command</key> <dict> <key>CommandUUID</key> <string>0001_DeclarativeManagement</string> <key>Command</key> <dict> <key>RequestType</key> <string>DeclarativeManagement</string> </dict> </dict> </dict> </plist>

There is a longstanding restriction payload for supervised iOS devices that disables "Erase All Content and Settings." We have been experimenting with supervised watches paired with supervised phones that have that payload applied, and yet "Erase All Content and Settings" remains available on the watch. Is this: – a) An error with our payload? Should we be sending something else? – b) A bug in watchOS supervision? – c) A deliberate design choice? If so, what is the rationale for preventing organizations from maintaining this very basic level of control over devices they may be configuring and dispatching into the field?

I encounter a connection error with Apple Configurator v2.18 when, after making changes in macOS Sequel 15.6.1, I want to apply and transfer the changes to the iPhone icon layout in iOS 26: Apple Configurator v2.18 crashes and returns an error message: ‘Try the operation again. If it fails, quit the application, launch it again, and try again. [NSCocoaErrorDomain – 0x1001 (4097)]’ I have done some research, and it seems that this bug has been identified and fixed in Apple Configurator 2 v2.19 (Build 10434). Have you encountered this problem? Do you know where to find version v2.19? This fixed version does not appear to have been released yet, and Apple support has been unable to help me. Thank you all for your help.

Hi all, I'm implementing Intune MAM to secure applications on iOS. However, I need my users to be able to save files (e.g. attachments in an email in the Outlook app) to iOS Files. To do so, I'm trying to put Files in exception of my Intune MAM policy and I need to obtain the Files "CFBundleURLSchemes" value from the info.plist file of the Files app. I'm not able to get that information. Are any of you able to get that somehow? Thanks!

We use Device Management Profile to restrict all apps from using camera on unsupervised devices. It works fine until iOS 26.1 beta. In iOS 26.1, only the camera icon is removed from Home screen, the third party apps can still use camera. In our scenario, the camera of employees' iPhones are disabled when they enter the factory and are restored when they leave. According to the documentation, disabling camera on unsupervised devices is deprecated. But supervision is not feasible option because these iPhones are owned personally by employees. Is there any new solution for camera restriction on unsupervised devices? Thanks.

When using the SoftwareUpdateEnforcementSpecific to target an update to iPad OS 18.7.1, will the update be triggered to be downloaded immediately after the iPad has an active Internet connectivity? Or, if the SoftwareUpdateSettingsAutomaticActionsObject download string is set to AlwaysOff, will this mean that the update enforced will not start downloading automatically, but only when the user decides? I am trying to understand how these two can be combined together or if they work independently, as while trying to enforce a specific version, we need to eliminate the possibility to download an iPad OS version using cellular data, as our devices have an eSIM installed and the cost of using that for the iOS updates will be quite high. Maybe there is a setting to only allow the iOS updates to be downloaded via Wi-Fi. Thanks!

Hi, I found In-App purchase feature is restricted even with User-based VPP. I understand Device-based VPP does not accept In-App purchase, however User-based VPP accept In-App purchase. (It works on iOS 15 device actually.) When I tried subscribe ChatGPT on iOS 26 device using User-based VPP, an error dialog is shown that explains In-App purchase is not allowed. sysdiagnose shows logs belog: 情報 2025-10-26 23:58:22.350841 -0700 storekitd [Client] (ChatGPT) Initializing client デフォルト 2025-10-26 23:58:22.353982 -0700 storekitd [Client] (ChatGPT) Initialized with server Production bundle ID com.openai.chat and request bundle ID com.openai.chat] デフォルト 2025-10-26 23:58:22.354020 -0700 storekitd [CanMakePayments] In-app purchase disabled because app com.openai.chat has MID based SINF In iOS 15 device, no storekitd logs are found and appstored and several processes seem to handle In-App purchase.

ABM has introduced a target date for moving a device from one MDM server to a new one. However, there's nothing in the API for setting that when you use the API to move MDM server Am I missing something or does it just not exist? Thanks Caroline

When an iOS 26.0 device is prepared in supervised mode, wifi connection screen is showing when the device is restarted. This wifi connect appears always on restart. I have tried using Apple Configurator GUI and Command line (cfgutil) command. In both cases, The behavior Wifi screen is showing up on restart for supervised mode. Cfgutil command: cfgutil -C {Certificate} -K {Key} prepare --supervised --name {NAME} --host-cert {Certificate} --skip-all Note: In non-supervised mode and other iOS, the wifi screen is not showing. Apple Configurator version: 2.18 iOS version: 26.0 Device model: iPhone 11 and above. Anyone else facing this issue? Any help is super appreciated.

Details: Device: iPhone 12 Pro Max System: iOS 26.1 beta 2 Issue Description: When testing MDM device restriction capabilities on iOS 26.1 beta 2, I found that the allowCamera restriction does not work as expected. Observed Behavior: • On a BYOD device: When allowCamera is set to false, the Camera and FaceTime apps disappear from the Home Screen, as expected. However, third-party apps (such as WeChat) can still access the camera and take photos. • On earlier versions (e.g. iOS 26.0.1): Setting allowCamera to false correctly blocks all apps, including third-party apps, from accessing the camera. Initially, I assumed Apple might have changed this restriction behavior so that allowCamera only applies to supervised devices. However, after testing on supervised devices, I found that even there, when allowCamera is set to false, the Camera and FaceTime apps are hidden, but third-party apps can still use the camera. This indicates that the restriction is not functioning correctly in iOS 26.1 beta 2. Expectation: When allowCamera is set to false, all camera access — including third-party apps — should be blocked. Request: Could someone from Apple’s development or MDM team confirm whether this is an expected behavior change or a potential bug in iOS 26.1 beta 2?

Hi everyone, I want to enable Single App Mode (SAM) for my custom app that’s installed on the device. However, my device is not supervised. Is there any way to: Enable Single App Mode without supervising the device? Any guidance or workaround would be appreciated. Thanks, Arnab Lahiri

Dear Apple Developer Team, Following the rollout of iOS 26.x and the introduction of the iPhone 17, we have identified a critical issue affecting Mobile Device Management (MDM) enrolment and restore operations. The issue appears to stem from the Device Management Profile configuration 'do_not_use_profile_from_backup' within Apple Business Manager (ABM), which currently defaults to False. This setting should be modified to True to ensure proper functionality. When the profile remains set to False, organisations leveraging MDM encounter repeated failures during device backup and restore operations. Specifically, restoring a supervised or managed device triggers a persistent MDM registration loop, effectively preventing deployment of iPhone 17 devices in managed environments. We recommend that Apple review and adjust the default Device Management Profile property within ABM to address this issue and restore full MDM compatibility for iOS 26.x and later.

After applying the MDM camera restriction on iOS 26.1 beta 2, the camera availability status is reported incorrectly. After applying the MDM camera restriction [UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera] return YES

We are managing VPP license switching operations using Apple's VPP Manage Licenses API. License information is managed by matching the “clientUserIdStr” data with the VPP account ID information managed on the server side. We received an inquiry stating that a VPP license did not activate despite the activation process being performed. Upon checking the API results, the update API returned a success status during execution. However, the “clientUserIdStr” information was missing from the license information field in the response of the information retrieval API. We kindly request your guidance on the reason why the “clientUserIdStr” information is missing when retrieving license information, and the steps to ensure this information is reliably returned.

I'm are attempting to use the device management migration feature in Apple Business Manager / Apple School Manager (for devices running iOS 26 / iPadOS 26) to re-assign managed devices from one MDM server to another. We followed the published procedure (select device(s) → Assign Device Management → Set deadline → Continue). However, we are observing that on the device side, no notification or prompt appears to the user (such as “Enrollment Required” or “Your organization requires this device to enroll in a different device management service”), even after the migration deadline has passed. Here are the environment details: Device OS version: (iOS 26.1) Device ownership: enrolled via Automated Device Enrollment MDM re-assignment in ABM: old MDM server（name: https://dev5.clomo.com/panel/mackey-dev/ ） → new MDM server (name: https://obliging-bunny-equally.ngrok-free.app/ ) Deadline set: (12/10/2025 12:00 AM) Network connectivity: confirmed online at deadline time We would like to know: Under what exact conditions will the device display the notification/prompt, and what common mis-configurations prevent it from appearing? Is there any device log or activity indicator in ABM/ASM to confirm that the migration instruction has been sent to the device? In cases where the prompt does not appear, what troubleshooting steps can we perform on the device (or in the MDM/ABM configuration) to correct it?
